Sentinel-2 Captures Lunar Image as Artemis II Journeys Around the Moon
A Copernicus Sentinel-2 satellite has captured an image of the Moon as part of a routine calibration process, utilizing an orientation typically not used for the Earth-observing mission. This event coincides with the ongoing Artemis II mission, which is currently traveling around the Moon with a crew of four astronauts, marking the first crewed lunar mission since 1972.
Sentinel-2 Lunar Imaging
The Copernicus Sentinel-2 mission, primarily an Earth-observing satellite, acquired the lunar image during a regular calibration procedure. This process involved rolling the satellite sideways to observe the Moon instead of Earth.
The method utilizes the Moon’s stable light intensity to detect and correct minor changes in the instrument’s performance, which is essential for maintaining data accuracy throughout the mission.
The captured image features a resolution of approximately 5 kilometers. It displays prominent lunar landmarks including the Tycho, Copernicus, and Kepler craters, as well as the seas of Rain, Serenity, and Tranquillity.
The Tycho Crater is visible as a large, pale impact crater in the upper-right portion of the Moon in this image. The Sea of Tranquillity is recognized as the landing site of the Apollo 11 mission in 1969, which marked the first human landing on the lunar surface. The Apollo 17 mission, the last crewed lunar landing, touched down in the Taurus-Littrow valley, located between the Sea of Serenity and the Sea of Tranquillity.
Artemis II Mission Progress
The Artemis II mission, which launched from the Kennedy Space Center in Florida, US, is currently traveling around the Moon with four astronauts aboard. The mission is designed to bring the Orion spacecraft and its crew within a few thousand kilometers of the lunar surface, offering views of the Moon.
The 10-day mission relies on the European Space Agency's (ESA) European Service Module to power and sustain the Orion spacecraft and its crew. This module is responsible for providing essential propulsion and life support throughout the journey.
The Artemis II mission is the first crewed lunar mission since Apollo 17 in 1972, with Europe contributing to its operations.
